Description

I had a problem with my roller installation. When I uploaded files (e.g. images), Roller did neither generate a thumbnail nor did detect the image size (-1 x -1 Pixel was shown).

Debugging the problem I found out, that roller did try to handle the image in /tmp/tomcat7-tomcat7-tmp/ which did not exist.

Creating the directory manually fixed the problem for me.

I think it would be best if the directory would get created automatically (which should be possible). Else it should get documented in the installation guide, that a temporary directory has to be created
